As title says, how much BTC will be in circulation within 2030?
The current circulation is about 1800 bitcoin per day. How can I calculate the possible circulation within 2030?
I have come to know that within May 2020, the rewards per block will be halved and eventually, there will be 900 bitcoin in circulation per day. So, when will be the next halving?
Is there any calculator which help you to calculate the circulation of BTC?

there are calculators online and websites that track halving and stuff like that and i am sure you will find them if you do a google search.

as for the mathematics behind it, things work this way:
- difficulty is set in a way that on average we see 1 block every 10 minutes on average. and when you calculate in long term you can use that approximation because the error in that is small.
- supply is distributed in form of block rewards and that is set in a way that it started from 50 btc/block and halves every 210000 block.

so you first calculate how many blocks are going to be found until a desired year (like 2030) starting from 2009 then break it into 210000 blocks and start multiplying each portion with appropriate reward:
- first 210000 * 50
- second 210000 * 25
...
- remainder (smaller than 210000) * respective reward
then add all of them together.

I think you are confusing circulation with mining production. They are not related. Bitcoins aren't consumed, so the bitcoins mined yesterday are in circulation today, too.

Anyway, this page shows the production schedule: https://en.bitcoin.it/wiki/Controlled_supply

Nope, I'm not confused. I am few a bit unfamiliar with the terms/words. A few mistakes are there in my presentation in OP.
Thank you for the link. This is what exactly I was looking for.
As per the above formula, the circulation should be 20500000 approx after 2030. Is it correct?

If you look at data posted on that link from odolvlobo, check second table and halving numbers. In year 2020 is 4 halving and in 2028 is 6 halving which is start with 20343750 bitcoins, and end with 20671875 bitcoins on 7 halving 2032, so you are right with your assumption.

Circulation of coins is only informative data, we all know that there will never be 21 million bitcoins in circulation - they are on blockchain, but private keys which control them are lost / destroyed over the years. Some speculation say that 3 to 5 million coins are losted so far, but it is almost impossible to determine that number with any certainty.

Yes, I had created a thread to have some valid discussion here about the lost Bitcoins. Approx. 4 million is lost and a minimum of 5 million will be lost after all the 21 million BTC get mined. My thread- https://bitcointalk.org/index.php?topic=5108242.0
But it's good for the bitcoin community who owns bitcoin, it was told by satoshi.
“Lost coins only make everyone else's coins worth slightly more. Think of it as a donation to everyone.” said by Satoshi.

what is certain is that the turnover of the bitcoin currency will be even greater, someday bitcoin will be used more as a payment currency for financial transactions than as an investment. thus the volume of bitcoin transactions will increase even greater. I am optimistic that a financial ecosystem will be created that can have such great capabilities in handling various financial transactions.

by 2030 we can expect btc  circulation would be around 18 millions btc as per the per market and 11 years ahead bitcoin  would be short of 3 millions less in circulation

It is not known how much bitcoin are permanently lost but the amount is in the millions.  So when you see the listed circulating supply on coinmarketcap it is not the actual true amount.  People are still losing coins everyday because of bitcoin owners dying with no relatives to access their keys.

i dont know about it, but i think that in 2030 all bitcoin in the world will already mined, so 21 Miliion bitcoin alraedy mined. which is it will give the decision is the bitcoin can rise up more and more or it will decreasing because they lost the popularity

and this is not right.
The difficulty (and halfing and supply) cannot be tricked that way that all is mined in 2030.

How did you come up with 3 million? If you've read the first few posts, you know that he's not asking how many bitcoins are in circulation not including lost bitcoins.


OP knows there are lost bitcoins and he even have a seperate thread for it

Technically it can be changed but that would result in a hard fork and it won't be called Bitcoin anymore.
  

I am thinking close to 90 - 100 billion given the current circumstance. It could be at least 5 times more if it picked up pace to even 50% of what it was in 2018 january.

For me,  I feel its inconclusive and can be hard to state because the amount of Bitcoin that  will circulate in the nearest future will have to do with how much it adoption and acceptation will be in the future.
So it's okay to say that that the amount of circulating  Bitcoin will double or triple if it's adoption increase than what it is now. Or might reduce if it has low adoption.

Bitcoin circulation every 4 years will always decrease from half, and that will definitely happen to reduce the circulation of bitcoin, and I think after 2030 the circulation of bitcoin will be around 225.

You just think but obviously havent done any research before saying that. I will take at least 100 more years until all bitcoin are going to be mined and that's because the difficulty of mining increases with each block that is created.
Regarding to OP, the circulation of bitcoin will most likely drop in time and that's because once bitcoin it's lost then it's gone for good and it's impossible to recover it. So what you should expect within 2030 is a smaller circulation of bitcoin than now.

With current difficulty it will take more than 100 years to mine all bitcoins in the world. After the halving has rate will increase and mining rewards will decrease periodically. After this event,low bitcoin supply will lead to increased prices.There is miscalculation in OP's argument.

I thought mining difficulty has already reduced because many btc miners were now quitting and moving unto other cryptos that are easier to mine  .  and also the mining dificulty could also depend on the mining hardware that you are using  and the factors sorround you  . 

But one thing is for sure .  the longer the bitcoin existed  , the more the supply that is produced and the price also grow bigger because the adoption is also growing .

Is it true? then whether bitcoin can return to the way it used to when the circulation continues to fall.
There will be many miners who choose to stop mining bitcoin if this is the case, and the bitcoin forecast will develop 10 years later will be lost

The total supply of BTC- 21 million. What did you mean through 225?

Bitcoin halving occurs every 210000 blocks. Current reward per block is 12.5 bitcoin. The next halving will occur in May 2020 and reward per block will be 6.25

Nobody is asking this question.  ???  Why do you want to know this?   Remember the reward per block will decline, but it does not mean that the supply will decline too, because people might be more willing to sell the coins that they are hoarding now, because they would get more money for it in the future. <Scarcity increase = Higher price>

Every Halving is a reminder for the average Joe, that less bitcoins might be available in the future and that prompts them to collect more.  ;D

Bitcoin's 2030 supply will be about 20 million. Bitcoin's 2030 and price I think it will hover between $8,000-$10,000.

It's because I'm trying to know more about bitcoin and learn how the total bitcoin eco works. I'm also creating a short analysis on bitcoin and its future. Probably I will come up with a survey soon.

if all are in line with expectations without any obstacles then by 2030 can make bitcoin as a currency to replace the dollar. and if that happens it will create a very stable business world without any pressure from any country. Bitcoin circulation is very dependent on the business actor itself. for example, traders use bitcoin only as a deposit, then the bitcoin that circulates becomes a little, this can affect the price and bitcoin can be lost from circulation because all business people save their bitcoin without wanting to circulate it.

nothing about what you two said are correct.
the circulation of bitcoin does NOT decrease. it is constantly increasing. what is decreasing and the first person is confusing it, is the new coins that are being created. meaning in early days (the first ~4 year) 7200 new BTC was being created per day approximately, and after that it halved to 3600 and now it is 1800.
i don't know where he even brought 225 from!

as for the second comment, miners won't leave because price is also rising with this change. for example when the reward/day was 7200, price was less than a dollar on average. so it was $7200 per day.
now that it is smaller at 1800 reward/day they are earning more than $7 million on average per day.
and that will only increase with time as bitcoin grows.

Thank you for the clarification although I have had gotten this info earlier. Both of the persons didn't check the earlier discussion in this thread.
I'm afraid about the next few years. What if bitcoin got a crash within next few years? The block reward will be decreased to 900/day. Will it affect the miners? Provided that back in days when it was $7200 per day, the difficulty was lower than now.

I feel it's a very lame question.it's not possible for anyone to predict the situation of bitcoin on 2030.we even don't know bitcoin will survive then or not.I rhink we shouldn't waste time thinking on this subject. Let's survive till 2030 first then think about btc.

why ? the guy is only asking and there is nothing wrong with that because the question is still related to bitcoin  . if you dont like it then leave it    . basic !


we cant exactly predict the exact situation but we can predict the situation verry closely  .  fluctuations ware still there but the circulation of bitcoin will increase .


btc already survive for a whopping of ten + years  .  we also know the usefulness of btc and day by day  , the popularity of bitcoin is spreading like a wildfire  . these are only few of the factors that will tell that bitcoin will exist for a very long time  .

Didn't you check the replies after the OP? It's possible to predict and people have shared the info even. About survival, why do you think BTC will not survive till 2030? For me, it will survive because it has reduced a lot of lengthy process of transferring money, it's decentralized, you are free to use whenever or whatever.
Reason on your argument?

       You refer to Bitcoin's mining production, not the Bitcoin daily circulation. Once every four years, Bithoin's mining production halves. Thus, in 2020, the half will be 6.25 BTC, and the next half will be in 2024. Thus, in 2024 there will be 3.125BTC.

This has been mentioned several times in this discussion. I have to lock this thread now.
